Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103142, here are decompositions:

  • 19 + 103123 = 103142
  • 43 + 103099 = 103142
  • 73 + 103069 = 103142
  • 211 + 102931 = 103142
  • 229 + 102913 = 103142
  • 271 + 102871 = 103142
  • 283 + 102859 = 103142
  • 313 + 102829 = 103142

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 103,142 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 103142 first appears in π at position 392,627 of the decimal expansion (the 392,627ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
